Murphy took a hard slide while covering second base Friday, and was removed from the game. He downplayed the injury, saying it was just a shin scrape. Manager Terry Collins still agrees with that assessment, saying Murphy could have played Sunday, but Collins wouldn't allow it.
Murphy hit .286/.319/.415 in 658 at-bats last year.
Ryan has been dealing with an oblique injury throughout camp. He said he's been improving every day. Ryan hit .197/.255/.273 in 319 at-bats last year.
Peavy is dealing with a finger injury, after cutting himself while fishing. He is slated to make his spring debut March 13, and remains on track for that start after a solid session Saturday. Peavy posted a 4.17 ERA in 144 2/3 innings last year.
Breslow has been able to throw back to back days of long toss, but remains a few days away from taking a mound. The team is taking it slow with Breslow after he dealt with a sore shoulder last spring. Manager John Farrell said "things are moving in the right direction" with Breslow.
The reliever posted a 1.81 ERA in 59 2/3 innings last year.
Irwin is dealing with a tender right elbow, but has started throwing. He plans to toss a bullpen session Monday. If that goes well, Irwin will likely make his spring debut Thursday. Irwin made one start for the club last year, posting a 7.71 ERA over 4 2/3 innings.
Locke took the mound Friday to test the injury, but stopped throwing after just a few pitches. "It still didn't feel right," Locke said. "I didn't see any point to keep throwing. So I stopped." Locke did not travel with the club this weekend, opting to remain with team trainers in order to map out a rehab plan.
Locke posted a 3.52 ERA in 166 1/3 innings last year.
The team has been cautious to overexert Wright this spring. He played in his first spring game Friday, but was held out of Saturday's game. Wright isn't dealing with any injuries, the team just wants to keep him healthy.
Wright hit .307/.390/.514 in 430 at-bats last season.
Peralta will attempt to play catch, and gauge his status after the throwing session. Peralta doesn't expect the injury to be a long-term thing. He was removed from Saturday's game due to neck issues.
Peralta posted a 3.41 ERA in 71 1/3 innings last year.
Gonzalez signed with the club Tuesday, and will need some time to get into game shape. If he can progress through minor-league games quickly, Gonzalez could make his spring debut soon. He shouldn't need a lot of work to be ready for the regular season, as he's a reliever.
Gonzalez is expected to compete for a spot in the Nationals bullpen. He posted a 4.68 ERA in 50 innings last year.
Odorizzi has worked with Alex Cobb during camp on the pitch. Cobb started throwing a splitter/changeup hybrid in 2009. It was a big part of his success in the majors last season. Odorizzi asked Cobb to show him how to grip the pitch, and has been working on it ever since. Odorizzi used his first two spring appearances to refine the pitch. "At this point there’s nothing wrong with throwing it to death," Odorizzi said. "My other pitches are fine right now. They feel perfect."
Odorizzi is fighting for the final spot in the team's rotation this spring. He posted a 3.94 ERA in 29 2/3 innings last year.
